Oxalis obtusa is a wonderful species, with the widest range of color imaginable, yellow, all shades of orange from buff to deep copper, white, many shades of pink, but best of all some have color combinations that are very striking. The petals are usually veined with a deeper color than the background, and there is a central ring that can be a completely different color.
Here to the left are O. obtusa 'Elizabeth', and O. obtusa 'Blush'. I have one species that is distinctly fragrant, the lovely O. obtusa 'Polished Copper' seen here to the right.
All of the Oxalis obtusa color varieties produce an abundance of flowers, and most mutiply readily. I am gradually producing new color combinations from random seeding. Yes, I do get seeding on my O. obtusas because I have so many different clones, but seed production is usually rare in the South African Oxalis species. Here are a few more:
Since I have 40 different O. obtusa colors listed on the web site, it is impossible to post pictures of all of them here, so check out the pictures on the web site: www.telosrarebulbs.com.
There is a sub-group within O. obtusa that produce very large flowers. I have listed two the in past as O. obtusa Large Form (a very dull name!), and I will be listing more. The flowers are up to two inches across (5cm), and are often marked on the back with red or purple striations. Here are a few below:
Some of these large form O. obtusa have been listed in the past as O. comosa, and an orange flowered one is still marketed under that incorrect name. O. comosa is quite different, with lavender flowers and tall branched stems.
There are now 125 different Oxalis species listed on the web site, and the Oxalis pages are now current for 2012, so whether you want to order or just enjoy the visual feast, check out the pictures.
